Plants take in CO2 to grow – all the Fossil Fuels were active biology in prehistory – when Saudi was a lush Eden.
It fed Rome in the days of the Roman empire – as some of our ol;der readers will recall. Those days chatting by the fountains in Rome – paradise.
Saudi only desertified in the little ice-age. But now we can turn the clock back. We get solar vacuum pumps from China. And as we suck sea water up only 1m, it boils – losing all salts and contaminants.
We transfer this to the high desert – or just to the desert edges. We dredge up sea wed, and wash it in river estuaries. We process this into thin mats, impregnated with grass seeds.
With the new pure water, we will get massive growth. We actually have to spray the fields with a little salt water, as salt is essential for life.
We plant seedling in soil balls at the field edges, to stop the new soil blowing away. We grow crops, and raise animals. What is now barren desert, is suddenly a lush area – sucking in all the CO2 it can get. Life today limits free average global CO2 at only 2 parts per million.Yuo have read 200ppm? Nuclear financed science fiction, for the stupid to believe: so obviously YOU did not believe it.
